2/1

The 2-Over-1 Game Force (2/1) is the biggest thing in the Bridge world since 5-card Majors. It has been around since the nineties, but Bridge innovations take a while to filter down from the expert level, so it has only recently become popular among Club players.

2/1 is more than just a Convention, but less than a complete new bidding System. It is an improvement to the standard 5-card Major system that most of us know and love. When you start using 2/1 you will find that most of your bidding stays just the same as it always has been. Your bidding after a 1NT opener doesn't change at all. Neither does your treatment of strong 2♣ bids, nor Weak 2's and preempts. All of your competitive bidding, overcalls and takeout doubles, stays just as you have it now.

In fact, there are only two aspects of your bidding that need to be modified.
The first modification, (and the name of the game), is the strength requirement to make a 2-level suit response to partner's opening 1 of a suit.

In standard methods you need 11 or more points and the bid is forcing for one round.

Using 2/1 you must have 13 or more points and the bid is forcing to game.

That may not seem like a big deal, but it is. When both partners learn in the first round of bidding that they are going to reach a game it eliminates most jump bids and keeps the bidding at a lower level while information is exchanged.

Be sure you understand that 2/1 applies ONLY to these six sequences:

NORTHSOUTH
12♣
NORTHSOUTH
12♣
NORTHSOUTH
12
NORTHSOUTH
1♠2♣
NORTHSOUTH
1♠2
NORTHSOUTH
1♠2
NOTE: In the last case, the 2 response requires at least a 5-card suit.
This lesson applies to those six bidding sequences.
BUT, many 2/1 players only consider five of those sequences as 2/1. They exclude the 1 - 2♣ sequence and use the 2/1 Game Force only after an opening bid of one-of-a-Major.

You may prefer to do it that way. If so, the 1 - 2♣ sequence is treated just as you are presently doing; Responder needs 11+ points, and it is forcing just for 1 round.

INITIAL RESPONSE

♠ 7 3
8 6
K Q 8 5
♣ A K J 4 2
Partner opens 1.
With 14 points you should bid 2♣.
This is the same bid you would make in standard bidding.
The difference is that in standard the bid is forcing for one round; using 2 Over 1 the partnership is now forced to game.

♠ 7 5 3
8 6
K Q 8 5
♣ A K J 4
Partner opens 1.
Here you bid 2♣.
With two 4-card suits respond up-the-line.
This is the same principle used in standard bidding.

♠ 7
8 4
K Q 8 5 3
♣ A K J 6 4
Partner opens 1.
This time you bid 2.
With two 5-card suits respond in the higher-ranking suit.
You might then bid 3♣ at your next turn.

♠ 7 4
A Q 8 3 2
A Q J
♣ 9 8 3
Partner opens 1♠.
ALERT!
Remember, you need a 5-card suit for this bid.
Since you have 5 of them, you bid 2.

♠ 7 4 2
A Q 8 3
A K J
♣ 7 4 2
Partner opens 1♠.
Here you can't say 2 with only a 4-card suit.
Instead you bid 2, a 3-card suit.
You plan to support ♠s at your next bid unless partner bids s.

♠ A K 8
9 8
K 7 5
♣ A K Q 6 3
Partner opens 1.
You should bid just 2♣.
It is true that with 19 HCP you have enough strength for a jump-shift to 3♣.
One of the benefits of playing 2/1 Game Force is that you almost never need to jump-shift. Of course you are thinking about a slam with this hand, but first you tell your partner you are forced to game, and start looking for your fit at a comfortable level. You will show your full strength later.

♠ Q 10 8 7
Q 8
7 4
♣ A K Q 4 2
Partner opens 1.
Bid 2 ♣.
Although a 1♠ bid would be acceptable it is probably better to bid your 5-card suit. Partner will bid ♠s if he has 4 of them.

♠ Q 10 8 7
K 8 2
7 4
♣ A K Q 4
Partner opens 1.
Bid 1♠, not 2 ♣.
Although you have the strength for a 2/1 response you should go ahead and bid the 4-card Major first. Contrast this with the previous example.

♠ 9 4
10 9 3
7 4 2
♣ A K Q J 4
Partner opens 1♠.
Do not bid 2♣, you only have 11 points.
Instead you must respond 1NT.
Note: this sequence will be explained later.

♠ 6 5 3
K 10 6 4
A K Q 7 5
♣ 5
Partner opens 1.
Do not bid 2 to show your 13 points.
Instead bid whatever bid you normally use in your methods to show a game forcing raise in partner's suit.
We suggest a splinter bid of 4♣.


OPENER'S REBID

You will find this to be the easiest part of 2/1.
Easy because the rebids are always natural, and are mostly pretty obvious.
Here they are in priority order:

Bid 3 if partner bid s and you have 3 or more.

♠ A 9 8 7 4
10 9 3
K Q 2
♣ A 4
The only 2/1 sequence where this can occur (immediate support with just 3 trumps) is when you open 1♠ and partner responds 2.
Bid 3 because you know there is an 8-card Major fit since partner's bid promises a 5-card suit.

♠ A Q 9 8 7 4
10 9 3
K 2
♣ A 4
Again you open 1♠ and partner responds 2.
Bid 3 because you know there is an 8-card Major fit.
Notice that even with 6 ♠s your priority is to immediately establish the 8-card fit as trump.

Bid a new Major suit with a 4+ card suit.

♠ A 9 8 7 4
A 10 9 3
K Q 10
♣ 4
You open 1♠ and partner responds 2♣.
Bid 2. Partner may well have a 4-card suit.
You may end up bidding notrump after partner's next bid.

♠ A Q 9 8
A Q 8 6 2
7 5
♣ 8 3
You open 1 and partner responds 2♣.
Bid 2♠ . In Standard bidding you would not make this bid since it is a reverse and your hand doesn't have the required strength. Playing 2/1, when the partnership is already forced to game, reverses do not require extra strength. The 2♠ bid might uncover a ♠ fit since partner might have 5 ♣s and 4 ♠s. Even if it doesn't, it shows partner where your strength lies so he can bid 3NT.

Rebid your own suit at the minimum level if you have 6 or more.

♠ A Q 9 8 7 4
10 3
Q 2
♣ A 7 4
You open 1♠ and partner responds 2.
Bid 2♠ to show your 6-card suit.
This also lets partner know you do not hold 3 s.

Bid 2NT with a balanced hand even if one of the unbid suits is not stopped.

♠ A Q 8 7 4
10 3
Q J 2
♣ A 10 4
You open 1♠ and partner responds 2.
Bid 2NT.
Partner will know you are balanced, probably with a doubleton .

♠ A K
K Q J 5 3
Q J 2
♣ 10 9 4
You open 1 and partner responds 2♣.
Bid 2NT.
You don't support ♣s with only 3, partner might have a 4-card suit.

Bid a new minor suit at the 2 or 3-level.

♠ 8 3
K Q J 5 3
A J 9 2
♣ Q 4
You open 1 and partner responds 2♣.
Bid 2.
The same bid you would make in standard bidding.

One caution applies here.
Try to avoid introducing a new suit at the 3-level unless you have either some extra strength or extra good distribution.

♠ K Q J 8 3
5 3
A Q 10 9 2
♣ 4
You open 1♠ and partner responds 2.
Bid 3.
You always show a second 5-card suit, even at the 3-level.
In other words, you have good distribution.

♠ K Q J 8 3
5 3
A Q 10 2
♣ A 5
You open 1♠ and partner responds 2.
Bid 3.
Your additional strength justifies the 3-level rebid, even with a 4-card suit.

♠ K Q J 8 3
5 3
Q 10 8 2
♣ A 5
You open 1♠ and partner responds 2.
Bid 2NT. With neither extra strength or distribution it is wiser to keep the bidding at the 2-level if you can.

None of the Opener rebids above were jumps. Opener does not need to make a jump rebid to show extra strength at this point. Since you are already forced to reach game you should bid slowly to first find out where you want to play, and worry about how high you want to go later.


RESPONDER'S SECOND BID

By the time Responder's second bid comes around you MAY have already agreed upon a trump suit.
The most likely 2/1 sequence for this to occur is this one:
OPEN
1♠
3
RESP
2
 

Here are various other scenarios.

Responder's first priority is to agree on the trump suit (or notrump) with this bid.

♠ A J
K J 7 3
K 9 8 5 2
♣ 9 4
OPEN
1♠
2
RESP
2
?
Bid 3.
You could not respond 2 initially with only 4 of them. When partner bids s you immediately agree, setting the trump suit. You might well decide to say 4 instead of 3, (see Fast Arrival below), but you don't need to worry that partner will pass you at the 3-level. She cannot, you are forced to game.

♠ A J
K J 7 3
K 9 8 5 2
♣ 9 4
OPEN
1♠
2♠
RESP
2
?
Bid 3♠.
You could not respond 2 initially with only 4 of them, and you could not support the ♠s with only a doubleton.
When partner rebids ♠s he shows 6 ♠s, but no 4-card suit so you agree on ♠s.

♠ A J
K J 7 3
K 9 8 5 2
♣ 9 4
OPEN
1♠
2NT
RESP
2
?
Bid 3NT.
Partner does not have 4 s.
Partner does not have 6 ♠s.
Partner probably does not have 4 s.

Responder's next priority is to rebid his own 6-card (or longer) suit.

♠ 9 3
A K 8 7 6 3
K Q 8
♣ 7 4
OPEN
1♠
2NT
RESP
2
?
Bid 3.
Partner does not have 3 s but may have 2.
Partner does not have 6 ♠s.

♠ 9 3
K 8 3
A K Q 8 7 5
♣ 7 4
OPEN
1♠
2
RESP
2
?
Bid 3.
Hopefully partner will bid notrump or rebid s.
But the best thing for you to do is describe your hand by rebidding s.

Responder's next priority is to try Notrump.
A notrump bid guarantees a stopper in the fourth suit.

♠ 9 3
7 4
K Q J 9 8
♣ A K 4
OPEN
1♠
2
RESP
2
?
Bid 2NT.
Unless partner now shows 6 ♠s the hand probably belongs in Notrump.
You do have the required ♣ stopper.

Responder's last resort is to bid the fourth suit.

This works much like the Fourth Suit Forcing convention used in standard bidding.
It does NOT indicate that you have strength in that suit; if you did you could bid Notrump.
It just means that you don't have any other bid at your disposal that describes your hand.

♠ K 3
A 6 4
K Q 9 8 5
♣ 6 5 4
OPEN
1♠
2
RESP
2
?
Bid 3♣.
You cannot support ♠s with only 2 of them.
You cannot support s with only 3 of them.
You cannot rebid s with only 5 of them.
You cannot bid Notrump without a ♣ stopper.
Last resort time - you bid the fourth suit.
You expect partner to bid 3NT if he can stop ♣s,
or to bid 3 if he has 5 of them,
or to bid 3♠ if he has 6 of them.



FURTHER BIDDING BY BOTH PARTNERS

Always keep in your mind that after a 2/1 sequence the partnership is forced to reach game.
This leads to an important idea, The Principle of Fast Arrival.
THE PRINCIPLE OF FAST ARRIVAL
When the partners are agreed on where to play the hand, an immediate game bid by either parther indicates that the bidder has nothing extra and no particular interest in trying to get to slam.

Here is one brief example (more are included in the Example Deals):

♠ 9 3
A J 9 7 4
K Q 8
♣ Q 9 4
OPEN
1♠
3
RESP
2
?
Bid 4.
You have a minimum hand and no interest in going beyond the game which you have already forced.
Don't think of this as a "shut-out" bid because partner is certainly entitled to continue on with a slam try of some sort. The 4 bid is just the best description of your own hand.

The flip-side of the Principle of Fast Arrival, (which should probably be called the Principle of Slow Arrival but for some reason nobody does), is that any other bid shows at least a little extra.

If you have agreed upon a suit, then "any other bid" would be a control-showing cue-bid. If you have agreed on notrump then "any other bid" would likely be a quantitative 4NT bid.

You don't need a lot extra to make this kind of bid.
All it really means is that you have a hand good enough that you didn't want to invoke Fast Arrival.

Here's an example of the flip-side:

♠ 9 3
A Q 9 7 4
K Q 8
♣ A 9 4
OPEN
1♠
3
RESP
2
?
Bid 4♣.
This time you have a somewhat stronger hand.
You aren't strong enough to start insisting on slam, but you are too good for Fast Arrival.
So you show your first-round control in ♣s, which you can do without going beyond 4. What happens next depends on partner; if he now just bids game you will pass happily, if he pursues slam you will cooperate.



WHEN 2/1 DOES NOT APPLY

There are two situations where the 2/1 Game Force does not apply.

When Responder is a passed hand 2/1 is OFF for two reasons. First, since Responder passed originally he obviously does not have 13 points. Second, a third-seat Opener may have opened light. So in this situation you just revert to Standard bidding.

If the opponents interfere immediately after the opening bid then 2/1 is OFF. There are other ways to make game-forcing bids, such as a cue-bid of the overcalled suit. However, if the opponent in the fourth seat interferes, (after Responder has already made a 2/1 Response), then the game-force is still on.

Here are two Responder examples:

♠ 9 3
A J 9 7 4
K Q 8
♣ 9 7 4
OPEN
 
1♠
RESP
pass
?
Bid 2.
11 points is not strong enough for a normal 2/1 response.
But since you have already passed partner knows you do not have 13 points.
This bid now shows at least 11 points.

♠ 9 3
A J 9 7 4
K Q 8
♣ 9 7 4
OPEN
1♠
OPP
2♣
RESP
?
Bid 2.
11 points is not strong enough for a normal 2/1 response.
But 2/1 is off because of the intervening bid.
This response shows at least 11 points.



2/1 SUMMARY

If partner opens 1♠, 1 or 1*, a non-jump response of 2 of a new suit requires at least 13 points and is forcing to game.
The partnership must either reach a game or double the opponents.
*Some pairs prefer to use 2/1 only when the opening bid is 1♠ or 1.

If the opening bid is 1♠, Responder needs a 5-card or longer suit to respond 2.

The Principle of Fast Arrival applies; an immediate game bid denies slam interest.

If the Opener is third or fourth hand, (partner having started with a pass), 2/1 is OFF.

If an opponent interferes immediately after the opening bid, 2/1 is OFF.


FORCING 1NT RESPONSE

Way up at the top of the page it was mentioned that there are TWO aspects of your bidding that must change if you play 2/1.
Here comes the second one.

In Standard bidding you must have 11 or more points to respond with a new suit at the 2-level.
So in Standard bidding, if you hold a 6-10 point hand, you respond 1NT whether or not you have a balanced hand. In other words, a 1NT response is the catch-all.

In 2/1 bidding you must have at least 13 points to bid the new suit at the 2-level.

See the problem?
How do you handle those 11-12 point hands which are too weak for a 2/1 response?
The solution is to expand the catch-all 1NT response to 6-12 points.

Easy enough to do that, but the increased range creates a new problem.
Suppose Opener has a relatively balanced 14-15 point hand.
A 6-10 point 1NT response could be passed without fear of missing a game, but if the 1NT responder might have 11-12 points then Opener dare not pass because in this case there might well be a game!

So when you use 2/1, you must also use the Forcing 1NT response.
FORCING 1NT RESPONSE

A 1NT response to a 1♠ or 1 opening bid, in first or second seat, shows 6-12 points and is forcing for 1 round.

Look at some examples of a Forcing 1NT Response.

♠ 7 5 3
8 6
Q 8 5
♣ A K J 4 2
Partner opens 1.
With 11 points you are not quite strong enough to bid 2♣.
So you bid 1NT instead, which is forcing for one round.
In standard bidding, of course, you would bid 2♣.

♠ A 6
Q 8 6
9 8 5 2
♣ 7 6 4 3
Partner opens 1♠.
With 6 points and a doubleton ♠ you respond 1NT.
In standard bidding you would make the same bid; this is often the case.

♠ K 9 4
Q 8 6
7 3
♣ A J 6 4 3
Partner opens 1.
With 11 points you cannot bid 2♣, that would be a 2/1 Game Force.
But you are too strong to bid just 1NT, that would show 6-10 points and would not be forcing.
So you jump to 2NT, inviting game.*
*Some comments are in order for this bidding sequence.

First, if you have decided to play 2/1 only after a Major suit opening then there is no problem, you just bid 2♣.

Otherwise you have to deal with the situation when partner opens 1 and you have 11-12 points and a ♣ suit.
The preferred solution is to adopt the following procedure after a 1 or 1♣ opening bid:
• A jump to 2NT shows 11-12 points with no 4-card Major and is invitational.
• A jump to 3NT shows balanced 13-15 points and is of course forcing to game.

♠ K 9 4
6
Q 7 3
♣ A J 6 5 4 3
Partner opens 1.
You are not strong enough to force with 2♣.
You are too strong to bid 1NT.
With the singleton, you are too unbalanced to jump to 2NT.
You cannot support s with only three cards in the suit.
You are way too good to pass.
When you do not have any call that is not a lie, you just choose the one that is the "smallest" lie. In this case, go ahead and bid 2♣.



OPENER'S REBID AFTER FORCING 1NT

Most of the time Opener's rebid after Forcing 1NT response will be the same as it would have been after a 6-10 point 1NT response.
Consider these examples:

♠ A K 9 7 5 3
7 4
K J 8
♣ 9 4
OPEN
1♠
?
RESP
1NT
Bid 2♠.
You have a minimum opening hand, and you should just rebid your 6-card suit.
This is the bid you would make whether you play Forcing 1NT or not.

♠ A K 9 7 5 3
7 4
A K J
♣ 9 4
OPEN
1♠
?
RESP
1NT
Bid 3♠.
You have an invitational hand, so you jump rebid your 6-card suit.
This is the bid you would make whether you play Forcing 1NT or not.

♠ A Q 7 5 3
A Q J 6
7 5
♣ 9 4
OPEN
1♠
?
RESP
1NT
Bid 2.
This bid does not show any extra strength, it just gives partner an additional option.
He is allowed to pass the bid if he wants.
This is the bid you would make whether you play Forcing 1NT or not.

♠ A K Q 7 5
A K J 6 3
5
♣ 9 4
OPEN
1♠
?
RESP
1NT
Bid 3.
You have a forcing-to-game hand, even if partner has only 6 points.
So you jump shift in your second suit.
This is the bid you would make whether you play Forcing 1NT or not.


Many other sequences will turn out the same in either method. The Practice Deals will show some of them.

The only time that Opener makes a rebid that is different from standard bidding is when he has a balanced minimum, 13-15 points, and only 5 cards in the opened (Major) suit.
Playing a 6-10 point 1NT response Opener's rebid was simple - PASS.
But playing Forcing 1NT response, Pass is no longer permitted, so some other action must be created.
Consider these examples:

♠ A J 8 7 3
K 9 4
K J 6
♣ 9 4
OPEN
1♠
?
RESP
1NT
Bid 2.
With standard bidding you would happily pass 1NT.
But now you can't. When you have to create a bid over a Forcing 1NT response, you are permitted to bid a 3-card minor suit. Responder, of course, must keep in mind that you might have bid a 3-card minor.

♠ A K 8 7 3
K 4
J 10 6
♣ J 9 4
OPEN
1♠
?
RESP
1NT
Bid 2♣.
When you have a choice of 3-card minors, choose ♣.
These choices correspond to the choice you make when opening a 3-card minor.

You might not like the thought of bidding a 3-card minor suit on the second round. That is particularly true when this is the very type of hand which you would love to just pass and let partner play 1NT. But when you play Forcing 1NT responses you have to get used to the idea that Responder will almost never get to play a 1NT contract - even if it turns out that would have been the best place for the partnership.

If you are thinking this is a huge drawback to Forcing 1NT, keep in mind that 1NT might not be the best landing place for these hands, even when Responder is weak.

Here are two possible scenarios built around that first example.

OPENER
♠ A J 8 7 3
K 9 4
K J 6
♣ 9 4
RESPONDER
♠ 6 5
A 8 2
Q 10 9 8 4
♣ 6 5 3
With standard bidding you would pass 1NT.
As you can see, 1NT is a poor contract.
Instead, with Forcing 1NT you would bid 2 which partner would pass.
This turns out to be an excellent contract.
1♠
2
1NT
pass

OPENER
♠ A J 8 7 3
K 9 4
K J 6
♣ 9 4
RESPONDER
♠ 6 5
Q J 8 7 5 2
Q 8 4
♣ 6 5
With standard bidding you would pass 1NT.
Again, 1NT is a poor contract.
Instead, with Forcing 1NT you would bid 2.
Partner would then say 2 and you would pass, again reaching an excellent contract.
1♠
2
pass
1NT
2

Those last two scenarios show off the positive aspects of Forcing 1NT response. But of course there are other scenarios which don't work out nearly as well. The thing to remember though, is that giving up the ability for Responder to play a 1NT contract is not all bad, plenty of times it works out for the best. And the advantages of using 2/1, (which must incluce Forcing 1NT response), are huge.

There is one thing Opener must avoid at all cost.
Do not panic and bid 2NT when you have a minimum hand.
A 2NT rebid is invitational and shows 16-18 points, just the same as in standard bidding.

RESPONDER'S SECOND BID WITH 6-10 POINTS

Remember: Responder's 1NT response was forcing on Opener. But, if Opener's second bid is a minimum response Responder is permitted to pass. In general, if Responder is in the 6-10 range, he will bid just as he would have in Standard bidding.

If Opener makes a minimum bid, either rebidding his Major suit, or bidding a new lower-ranking suit then Responder has several options.

RESPONDER'S SECOND BID WITH 11-12 POINTS

With 11 points in support of ♠s, Responder might have made an immediate limit raise.

However, by first responding 1NT Forcing, then jumping in ♠s, he describes a limit-raise strength hand with only 3-card trump support. An immediate limit-raise is used with 11-12 points and 4-card support.

With 11 points in support of ♠s, Responder plans to make a limit-raise AFTER the Forcing 1NT.

When Opener merely rebids ♠s, showing a 6-card suit, Responder can now just bid 3♠ to show the same hand as before, and invite Opener to bid game.

Responder must be cautious about supporting Opener's second suit when it is a minor, since very often it will be a 3-card suit. It is best to support only with 5, or a very good 4.

Here Responder supports Opener's s, but Opener is not strong enough to try game.

WHEN A 1NT RESPONSE IS NOT FORCING

• When the Opening bid is 1♣ or 1.

After an opening bid of 1♣, a 1NT response is not forcing.
It shows 6-10 points and no 4-card Major, just as it has always done.
This does not create a problem because there is no 2/1 sequence after a 1♣ opening bid so you don't need the expanded 1NT response range.

After an opening bid of 1, a 1NT response is also played as non-forcing, showing 6-10 points and no 4-card Major suit. This agreement does have a problem. How will you respond holding 11-12 points and a ♣ suit? You cannot say 2♣ since that would be 2/1 Game Force, and you are too strong to respond 1NT.

A good method to handle many of these hands is to use a jump to 2NT to show 11-12 points and reasonably balanced. Then, you can use a jump to 3NT to show 13-15 points and balanced. Many partnerships give a 2NT response to a Major Suit opening some other meaning, (Jacoby 2NT for example), so this agreement only applies after a Minor Suit opening bid.

• When Responder is a passed hand.

There is no need for a Forcing 1NT response when Responder has already passed since in that case 2/1 Game Force would not apply and Responder could bid a normal 2-of-a-suit with an 11-12 point hand, and 1NT with a 6-10 point hand. In any case, some pairs will be using Reverse Drury or some other convention after a third-seat, (possibly light), Opening bid.

• When the Opening bid is followed by an immediate Overcall or Double

If the Opening bid is followed by immediate enemy interference, both 2/1 and Forcing 1NT Response are OFF.
All bidding becomes "Standard" bidding, with the 1NT response showing stopper(s) in the Overcalled suit, and 2-of-a-suit showing 11 or more points.


FORCING 1NT SUMMARY

If partner opens 1♠ or 1 in first or second seat, a 1NT response shows 6-12 points (and no ♠ suit if the opening bid was 1). The bid is forcing on Opener for 1 round.

Opener usually rebids the same as in standard bidding, EXCEPT when he holds a balanced 13-14 point hand which he would pass in standard bidding. In this case he bids his longer minor suit (♣s with equal length in the minors).

Responder may pass Opener's minimum rebid, and with 6-10 points should usually do so.
With 11-12 points Responder should strive to find a game-invitation bid.

Forcing 1NT does not apply after a 1♣ or 1 opening bid.
Forcing 1NT is OFF if Responder is a passed hand.
Forcing 1NT is OFF if Responder's RHO Overcalls or makes a Takeout Double.
